Kamala Harris was the running mate of Joe Biden in the 2020 U.S. presidential election. Joe Biden, the Democratic presidential nominee, chose Kamala Harris as his vice-presidential running mate in August 2020. Harris made history as the first Black and first Asian American woman to be nominated for vice president by a major political party.

Additionally, in a later campaign for president in 2024, Kamala Harris revealed in her memoir that her first choice for a running mate was Pete Buttigieg, the former Transportation Secretary, but she ultimately picked Minnesota Governor Tim Walz, considering the political risks involved with their ticket.
